5 6 cpuidle governors
7 8 9 10 11cpuidle governor is policy routine that decides what idle state to enter at
12any given time. cpuidle core uses different callbacks to the governor.
13 14* enable() to enable governor for a particular device
15* disable() to disable governor for a particular device
16* select() to select an idle state to enter
17* reflect() called after returning from the idle state, which can be used
18 by the governor for some record keeping.
19 20More than one governor can be registered at the same time and
21users can switch between drivers using /sysfs interface (when enabled).
22More than one governor part is supported for developers to easily experiment
23with different governors. By default, most optimal governor based on your
24kernel configuration and platform will be selected by cpuidle.
